So, NASA, is in the process of working on some of this. They’re trying to come up with a new ATC model which will work better for drones / eVTOL air taxis / etc. Some of the ideas are around “carving” out corridors, where you woul

Just curious, how well were you compensated? Did you work on the radio side doing embedded stuff / math, or server software?

I guess what frustrates me is stuff like googling "ad9361 sync" gets you: https://wiki.analog.com/resources/eval/user-guides/ad-fmcomm... Whereas googling this about the LMS7002 seems to show you ca

This is a really cool, valuable, important project. It's a little bit of a bummer that they went down the USRP Route ( https://powderwireless.net/equipment ), as USRPs are really not accessible to many people (price poin

PTrace comes with some pretty big restrictions. For one, no process can be ptraced by two processes at the same time. User notify aims to be a safer way to do this that doesn’t require the overhead and complexity of ptrace.

I also pay $dollars/year for Google. Turns out, when you start paying people money, and it becomes a legal liability for them to screw up, they act...better? I have a one-click button to download all my data from Google (which turns ou

Personally I use login with Google because: 1. I “trust” google auth - I know they won’t store passwords in plaintext or anything funny like that 2. It’s a centralized place I can use to rotate my keys 3. I can revoke accounts Signing up vi

Yelp was severely impacted by "the shutdown". I'm surprised that they cannot capitalize on this data and start a hedge fund or similar -- or at least sell it to a hedge fund in exchange for keeping them afloat a while longer.

It's also bandwidth right? What's the throughput on shortwave? I believe that Starlink promises mbps+. I imagine there are applications you can implement on higher bandwidth are more interesting? Was Pilosoft always an HFT thing?

HFT firms make a lot of money...but space launch is even more costly. :(

I remain convinced that this is Starlink's short-term customer if their promises are true. They are doing transmission via optical as the crow flies. If they're doing O-O, or even low latency O-E-O, they can beat transatlantic fib

I don't understand how this meme of "Corporations sell your data" came about. Google has perhaps the world's largest trove of information about people, but do you see it ever leave their iron grip? No. Same with Facebook

The real question I have is where is this money going? I've looked at positions at NSA, and I know at lease one person that works there. They aren't making heaps of money. How are they recruiting so many qualified individuals?

I wonder why SHA-256, and not BLAKE2(b/s) or BLAKE3. BLAKE3 is significantly faster.

I would be sad if Gorillaz never performed live again. I’ve seen their live shows and they were truly epic in size. They had 50+ people on stage, and an awesome video mix.

At least in regards to the later point about the price of a camera. I think my old camera was about $3,000 with the lenses (7D mk ii). I had it for 5 years. In that time, I’ve bought 4 phones. The cheapest of which was $700, and the avg pri

So, no idea the cost of O-O amplification or O-E-O these days, but it's expensive. You have to run power (usually there's power with the optics), and the bigger problem is real estate (At least in urban areas). 100x lower signal l

SQLite is a much younger project than I thought it was. Given the ubiquity, and capabilities that it provides, it's impressive. On the other hand, Linux and Python are 29 years old. Postgres, in its current form is ~23 years old. It st

If it makes people feel better, and gets people to stop being unreasonably unhappy about something harmless, who are we to ruin that for them? I guess we could be opening ourselves up to a slippery slide, or some danger that people make uns

These bugs are not specific to MySQL. The bug around context closing the connection resulting in a txn not having an explicitly successful abort / rollback is a problem as well because conn.Close gets called in a goroutine when context

user namespaces are a super rad feature. They've protected us at $WORK from multiple vulnerabilities that have come out.
